Abstract
A variable-geometry turbocharger (1) with a vane lever (11) that provides a stop function at full open position of the guide vanes (8). The integrated vane-open stop controls the full open position of the VTG mechanism. A vane lever (11) preferably has an integrated protrusion (50) that functions as a vane-open stop that contacts an adjacent vane lever (11), an integrated bolt (56), or the upper vane ring (16) at the full open position to regulate maximum exhaust gas flow to the turbine wheel (5).
